And, it's true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.

    Ravi has spoken of his own journey only in bits and pieces in his other books and talks. It is a journey that has led him beyond his family and culture into a revelation that replaced pantheism with monotheism, and into a relationship with a God the vast majority of his people do not worship. From this new understanding birthed in him by the founder of Christianity, Ravi has gone forward to teach as one of our generation’s great apologists.A life lived in Christ is the greatest argument of all for the living God. Ravi urges the reader to look at the lives that have turned the hearts of people into movements for Christ. In the first three centuries of the church, the Apostles and followers like Polycarp and Tertullian and Origen demonstrated with their lives the truth of the resurrected Christ. A whole line of witnesses from every generation succeeded these who walked in the footsteps of Jesus, with names like Augustine, Catherine of Sienna, Bernard of Clairvaux, Luther, and Wesley leading the procession.But history begins on an individual level.Ravi shows readers his life, in its successes and failures, in its existence in the East and in the West, and in his attempts to bring the truth of Christ to those in any culture who don’t know him. The Hebrew poet has said that a life rich in experiences is a life from which others can learn.This book is about Ravi’s journey, from meaninglessness to the abundant joy of Christ, from East to West and back again, in the all-consuming passion of letting the world know about true freedom, and in whom that freedom is found.

    This is the gripping story of how God took a young, half-starved boy from a poor village in Henan province and placed him on the front line for Jesus, in the face of impossible odds. Instead of focusing on the many miracles or experiences of suffering, however, Yun prefers to focus on the character and beauty of Jesus.

You will remember where you were the first time you read this life story. It's a watershed book that will turn the reader to prayer and praise.

    I think he will be a most interesting tutor to have.Interesting? Yes, he's certainly that, said the man, who I later learned was J. R. R. Tolkien. You'll never get to the bottom of him.Over the next twenty-nine years, author George Sayer's first impression about C. S. Lewis proved true. He was interesting; but he was more than just that. He was a devout Christian, gifted literary scholar, best-selling author, and brilliant apologist. Sayer draws from a variety of sources, including his close friendship with Lewis and the million-word diary of Lewis's brother, to paint a portrait of the man whose friends knew him as Jack.Offering glimpses into Lewis's extraordinary relationships and experiences, Jack details the great scholar's life at the Kilns; days at Magdalen College; meetings with the Inklings; marriage to Joy Davidman Gresham; and the creative process that produced such world-famous works as the classic Chronicles of Narnia, Mere Christianity, and The Screwtape Letters.This book is an intimate account of the man who helped--and through his works, continues to help--generations hear and understand the heart of Christianity.
